FILLING-END CLEARER.

' Application fiieanayia, 1925. Serial 110,109,039.

Thisinvention relates to replenish ing looms and -more particularly tofilling end clearers employediinlsuch looms to withdraw theifilling endfrom the shuttle on call for replenishment tolprevent the production ofimperfect cloth.

It has heretofore been proposed to provide filling replenishingloomsVwith-filling end clearers in which filling catcher has; beenmounted in front of the lay, and the filling end clearer has beenkmountedupon the lay to pass frontwardly of the V filling end catcher onbeat-upmovementjofthe lay to permit the discharged filling carrier topass between the catcher and clearer upon replenishment of filling. a v

In looms of this general character it some-. times happens that thefilling carrier or bobbin itself may be caught between the filling endcatcher and the filling end clearer, and in such case a smash is liableto occurasthe lay goes back after replenishment of filling; i

V One of the objects of the present invention is to provide a fillingend catcher and a filling end clearer wherein means are embodied toprevent a; smash should thefilling carrier or bobbin be: caught betweenthe filling end catcher and the filling end clearer as the lay goes backafter replenishment of filling. I or g In accordance with thepresentinvention,

the filling end catcher is mounted infront.

of the lay and the filling end clearer is mounted upon thelay topassfrontwardly of the filling end catcher on heat-up moveinent of the lay,andso mounted upon the lay that sho'uldfa filling carrier or bobbincaught betwen the catcher and clearer, theilatter may yield in the planeof movement-of the lay as Ithelatter goes back after replenishment, toprevent the occurrence of a smash or breakage of parts. I V

The invention andnew features thereof will best be made clear from thefollowing description and the accompanying drawings of one good formthereof. 1 U 1 3' In the'drawing'sL,

V Fig. 2 is aidetail planzview showing therelation of parts when a"filling carrier or bobbin gets caught between the fillingend catcherand filling end clearer'askthe lay goes back following replenishment'offilling.

The loomjillustrated in the accompanying drawing may be of the usualautomatically,

filling replenishing type, comprising'a frame ilzwhich'supports at itsreplenishing side a hopper stand 2 provided with the rotary hopper 3which'carries the usual series of fresh filling carriers 4 adapted to besuccessively presented abovethe'lay when the, lattcrisintransferringposition.

The parts sofandescribedare "or may be of usual'c'on-y struction and furtherexplanation thereof the filling end catcher is mounted, upon the loomframe in front of the lay, and when the; lay moves frontwardly thefillingend catcher 1 takes a. position back of the bottom opening.

in: the shuttle box, 'so'that the ejected filling 1 carrier may passfrontwardly of thefillingj 7 end catcher. 'In thepresent instance: of.the i invention, theffilling end catcher .llflis mounted upon the studor; dead *shaftglQ extending from the loom frame,',a-nd such,

ids andjfrom the front of the loom; and to'this t,

- shown and explained in the patent to Edward S. Stimps on, Elm1,422,728, datedxq'luly Mountediupon the lay is the filling end clearerwhich on frontward movement of the lay passes frontwardly of the fillingend catcher a 'sufiicient distance topermit the ejected filling carrieror bobbin to pass between it and the ifilling end catcher, so that onbackward movement of the lay'foll'ow ng replenishmena the filling endmaybe given a backward'bend about the filling end catch er as thefilling'end clearer recedes or moves backward with the lay. v i

The filling end clearer comprises an arm 17 carried by the lay, and asthe lay moves frontwardly the filling .end clearer passes below andclosely adjacent to the laterally extending arm 13 of the filling endcatcher so that should the discharged filling carrier or bobbin beejected from the shuttle at such times, it will pass between the fillingend catcher and filling end clearer and on backward movement of thelaythe filling end a will be given a whip-like'movement to withdraw it fromthe shuttle and shuttle box.

It sometimes happens, however, that a filling carrier or bobbin will getcaught between the filling end catcher and filling end clearer, and oneof the important features of the present invention is to provide aconstruction which, unoer such conditions, will prevent the smash orbreakage of parts.

In accordance with the present invention, therefore, the filling endclearer or arm 17 is mounted upon a pivotal support carried by the lay,the axis of which support is vertical with respect to the lay race, withthe result that the filling end clearer may yield frontwardly in a planeparallel'to the lay 'movem ent should a filling carrier or bobbin,befcaught between the catcher and clearer, and such frontward swingingmovement of the filling end clearer in a plane parallel .to laymovement, enables the filling end clearerto disengage t'hefillingcarrier or bobbin as the lay goes back after replenish- 11181111;

More specifically stated, the lay is provided with a bracket 18 whichmay be adjustably secured thereto by a bolt 19 passing throughan'elongated slot 20 formed in the "bracket, and extending from thebracket is" a lug 21 in which is securedthe pin 22 constituting the axisof swinging movement of the clearer. The clearer or arm 17 is mountedupon the pin 22 for swinging move ment in the plane parallel to laymovement, and may be conveniently secured in position on the pin .22 bya head'23 formed on the pin 22.

The clearer or arm 17 is'normally under the influence of a springtending to mains tain the clearer or arm 17 in its normal position.'ln'the'present instance of the invention, the pin 22 is secured to thelug 21 by a cotter-pin 2 1 and a spring 25 placed about the pin 22 hasone secured to the lug21 and the other end secured at 26 to the arm orclearer 17, the construction being such that the normal action of thespring 25 is to maintain the clearer in its normal position, asindicated in Fig. 1. g f

"desired, a washer or sleeve 27 may be interposed between the hubportion of the clearer or arm 17 and the lug 21 in order to protect thespring from foreign' matter. The arm 17 is provided with a stop 28which, under the action of the spring 25, normally rests against theface of the bracket 18, as indicated in F 1. As h'ereinbefore noted, theaxial support for the movement ofthe swinging arm 17 isvertical-with-respect to the lay or lay race and consequently theswinging movement of the clearer or arm 17 is in the direction of laymovement, so

that should a filling carrier or bobbin be caught between the fillingend catcher and the filling end clearer after replenishment of filling,the clearer or arm 17 may yield in the plane of lay movement'as the laygoes back, and finally be drawn across and treed from the fillingcarrier or bobbin to permit the latter to drop when thelay hasapproached or is in its rear position.

The action of the parts in preventing a smash is represented in. detailin Fig. 2, wherein it will be noted that the lay ismoving'backwardly andthe filling carrier or bobbin 6 has beencaught between the filling endcatcher and the filling end clearer when the lay wasin front position.As the lay continues its backward movement, as indicated by the arrowinFig. 2, the filling end clearer or arm 17'will be drawn across andfinally freed from the trapped filling carrier or bobbin and therebyprevent a smash or breaking of parts;

Since it is desirable that the filling end' lll! It will also beobvious'that when a filling carrier or bobbin has been trapped, asindicated in F '2, and the laymoves backward to disengage the fillingend clearer from the bobbin or filling carrier, the spring from thedischarged filling carrier as the dischargeof fil lay goes back and thefilling end clearer is drawn across and freed from the filling carrieror bobbin.

What is claimed is: Y 1. In a filling replenishing loom, the comboXhaving an opening for the discharge of filling carriers, a filling endcatcher yieldingly mounted in front of the lay, and a filling endclearer carried by the lay to pass frontward of the filling end catcheron beat-up movement of the lay and yieldingly mounted to cause its freeend to swing in a plane parallel to the lay movement to trip past anddisengagethe filling carrier'to prevent a smash should suchfillingcarrier be caught-between the filling end catcher and filling endclearer as the lay goes back.
